Abstract
The invention discloses a manufacturing process of a rubber tube. The manufacturing process includes the following process steps of 1, raw rubber treatment; 2, matching and mixing, wherein butyl rubber, sulphur, zinc oxide, magnesium oxide, butadiene-styrene rubber, acid acceptor, paccelerant, microcrystalline wax, chlorinated polyethylene, barium carbonate, vermicular graphite carbon, aluminum silicate, antiager and a compounding agent are placed in a rubber mixing mill according to a formulation to be mixed into glue; 3, still standing, 4, remilling; 5, vulcanization; 6, trimming and inspection. In the course of the process, raw rubber treatment is plastication on rubber, the physical and mechanical property of a rubber product can be improved through mixing, plastic rubber is converted into elastic rubber or hard rubber through vulcanization, and the raw rubber treatment, plastication and vulcanization are important parts in the course of the process.
Description
Technical field
The present invention relates to rubber item field, be specifically related to a kind of manufacture craft of rubber hose.
Background technology
Rubber hose is the class tubular rubber goods in order to delivering gas, liquid, pulpous state or particulate materials.Be made up of inside and outside glue-line and casing ply, the material of casing ply can use cotton fibre, various synthon, carbon fiber or asbestos, steel wire etc.The inside and outside glue line material of general sebific duct adopts natural rubber, styrene-butadiene rubber(SBR) or cis-1,4-polybutadiene rubber; Oil resisting rubber hose adopts chloroprene rubber, paracril; Acid and alkali-resistance, high-temp .-resistant rubber duct adopts ethylene-propylene rubber(EPR), viton or silicon rubber etc.Sebific duct has been applied to the numerous areas that life is produced, conclude applying working condition, common tubing comprises: hydraulic pipe, hot-water line, vapour pipe, Hai Yongguan, food-drink pipe, blast main, welded tube, gas line, vent-pipe, materail tube, transition pipeline, chemical tube, high pressure pipe etc.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide a kind of in detail containing the manufacture craft of the rubber hose of formula.
The technical problem that the present invention solves can realize by the following technical solutions: a kind of manufacture craft of rubber hose, comprises following processing step:
(1), rubber process: be obtain the rubber that water-content is less than 1% after raw material dehydrates by natural rubber;
(2), proportioning is mixing: according to formula by isoprene-isobutylene rubber 80 ~ 120 parts, 1 ~ 2 part, sulphur, 3 ~ 5 parts, zinc oxide, 3 ~ 5 parts, magnesium oxide; butadiene-styrene rubber 20 ~ 40 parts, acid-acceptor 3 parts, promotor 0.3 ~ 0.5 part; microcrystalline wax 3 ~ 5 parts; chlorinatedpolyethylene 3 ~ 5 parts, barium carbonate 10 ~ 12 parts, compacted 8 ~ 10 parts, black carbon; pure aluminium silicate 50 ~ 80 parts, 4 ~ 8 parts, anti-aging agent and Synergist S-421 95 are placed in mixing plastic in rubber mixing machine;
(3), park: the rubber after mixing is parked 20 ~ 24 hours in drying room;
(4), back mixing: dried remaining rubber is put into again rubber mixing machine and new rubber unvulcanizate heat refining again;
(5), sulfuration: rubber is issued biochemical cross-linking reaction with sulphur in the condition heated and becomes tridimensional network;
(6), deburring inspection: the rubber after sulfuration is carried out pruning and checks its continuity and plasticity-.
Preferably, the Synergist S-421 95 in described step (2) is the even proportioning of weighting agent, strengthening agent, promotor, vulcanizing agent, anti-aging agent, scorch retarder.
Preferably, the usage quantity of the sulphur in described step (5) is 18% ~ 25%.
Beneficial effect is: in this technological process, the process of rubber is also plasticating to rubber, rubber molecular weight and viscosity can be reduced to improve its plasticity-, reach the object of plasticising, the mixing physical and mechanical properties that can improve rubber item, improve processing and forming technology, reduce production cost, all there is decisive influence to half-finished processing performance and final product quality.And parking afterwards twenties hours can be all dry by rubber completely, in case cause the incomplete problem of sulfuration in sulphur process afterwards, back mixing can improve the utilization ratio of rubber, also save cost, sulfuration is the process that plastic rubber is converted into elastic caoutchouc or vulcanite, the process of the net high-polymer that the linear polymeric in rubber is formed by crosslinked action is the important component part in technological process.
